To invest in Bitcoin, you definitely need a reasonable income, which we also refer to as a discretionary income position. It is very important to invest in Bitcoin for the long term in the current position, because Bitcoin investment plays the most important role in your future financial independence. If you invest in Bitcoin according to the DCA method, it will be much easier for you to maintain your Bitcoin investment.
So start investing in Bitcoin right now and keep it for a long time and take the opportunity to buy Bitcoin repeatedly, you will definitely be able to achieve success quickly. And you will also be able to accumulate more Bitcoin in your portfolio, with which you will be able to eliminate financial deficiencies.
No, you don't need a reasonable income because someone with low income can have a discretionary income from his income and invest in bitcoin.
Income is different from discretionary income because your discretionary income is your extra cash that you don't need for any important needs and can do without it even if you loss it. It can be gotten from your income or somewhere else. While your income is what you need to take care of your basic needs and monthly expenses. Some people have income but they don't have discretionary income.
Therefore, what a new beginner needs to start his bitcoin investment is his discretionary income. It mustn't be big, be it as low as $10 and above is enough to get started.
Sometimes lump sum investing does better, and in other situations, more flexible or active strategies can outperform DCA.
I believe there is no other strategy that can be more active than DCA in the sense that DCA keeps you in the market always accumulating bitcoin either weekly or monthly consistently overtime till you reach your bitcoin investment. However, I believe that to increase your bitcoin portfolio faster overtime is when you mix all three strategies.
You keep your weekly DCA ongoing, lump sum whenever, you have extra funds and keep a reserve funds to buy more at the dip. Buying aggressively, when you have the financial strength and front loading your bitcoin investment is also a good way to increase your bitcoin portfolio faster.
